| Abstract: | Based on the problem that sewage is difficult to recycle in the production of sodium fluosilicate with sodium chloride as raw material, sodium sulfate is used as raw material to produce sodium fluorosilicate. The production process and production control indicators are introduced; The sewage in fluorine sodium silicate production is used to filter phosphate according to two stages of production test, after transforming, production technology and the quality of fluorine sodium silicate products are ensured, the comprehensive utilization of sewage is realized. |
